Cornaceae
The Cornaceae are a cosmopolitan family of flowering plants in the order Cornales. The family contains approximately 85 species in two genera, ''Alangium'' and ''Cornus''. They are mostly trees and shrubs, which may be deciduous or evergreen, although a few species are perennial herbs. Members of the family usually have opposite or alternate simple leaves, four- or five-parted flowers clustered in inflorescences or pseudanthia, and drupaceous fruits.Kubitzki, K. (2004). Cornaceae. In ''The Families and Genera of Vascular Plants Volume 6: Flowering Plants: Dicotyledons: Celastrales, Oxidales, Rosales, Cornales, Ericales'' (Kubitzki, ed.). Springer-Verlag, New York. The family is primarily distributed in northern temperate regions and tropical Asia. In northern temperate areas, Cornaceae are well known from the dogwoods ''Cornus''. The systematics of Cornaceae has been remarkably unsettled and controversial, and many genera have been added to it and removed from it over time. (One ...

Dogwood
''Cornus'' is a genus of about 30–60 species of woody plants in the family Cornaceae, commonly known as dogwoods, which can generally be distinguished by their blossoms, berries, and distinctive bark. Most are deciduous trees or shrubs, but a few species are nearly herbaceous perennial subshrubs, and some species are evergreen. Several species have small heads of inconspicuous flowers surrounded by an involucre of large, typically white petal-like bracts, while others have more open clusters of petal-bearing flowers. The various species of dogwood are native throughout much of temperate and boreal Eurasia and North America, with China, Japan, and the southeastern United States being particularly rich in native species. Species include the common dogwood ''Cornus sanguinea'' of Eurasia, the widely cultivated flowering dogwood ''( Cornus florida)'' of eastern North America, the Pacific dogwood ''Cornus nuttallii'' of western North America, the Kousa dogwood ''Cornus ...

Cornales
The Cornales are an order of flowering plants, early diverging among the asterids, containing about 600 species. Plants within the Cornales usually have four-parted flowers, drupaceous fruits, and inferior to half-inferior gynoecia topped with disc-shaped nectaries. Taxonomy In the classification system of Dahlgren the Cornales were in the superorder Corniflorae (also called Cornanae). Under the APG IV system, the Cornales order includes these families: * Cornaceae (the dogwood family) * Curtisiaceae (cape lancewood) * Grubbiaceae (the sillyberry family) * Hydrangeaceae (the hydrangea family) * Hydrostachyaceae * Loasaceae (the stickleaf family) * Nyssaceae, (the tupelos) The oldest fossils assigned with confidence to the order are '' Hironoia fusiformis'', described from Coniacian age Japanese coalified fruits, and '' Suciacarpa starrii'' described from American permineralized fruits of Campanian age. Phylogeny The Cornales order is sister to the remainder of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alangium
''Alangium'' is a small genus of flowering plants. The genus is included either in a broad view of the dogwood family Cornaceae, or as the sole member of its own family Alangiaceae.Qiu-Yun (Jenny) Xiang, David T. Thomas, and Qiao Ping Xiang. 2011. "Resolving and dating the phylogeny of Cornales - Effects of taxon sampling, data partitions, and fossil calibrations". ''Molecular Phylogenetics and Evolution'' 59(1):123-138. ''Alangium'' has about 40 species, but some of the species boundaries are not entirely clear.Chun-Miao Feng, Steven R. Manchester, and Qiu-Yun (Jenny) Xiang. 2009. "Phylogeny and biogeography of Alangiaceae (Cornales) inferred from DNA sequences, morphology, and fossils". ''Molecular Phylogenetics and Evolution'' 51(2):201-214. The type species for ''Alangium'' is ''Alangium decapetalum'', which is now treated as a subspecies of ''Alangium salviifolium''.''Alangium'' In: Index Nominum Genericorum.

Alangiaceae
Alangiaceae was recognized as a small family of small dicotyledon trees, shrubs or lianas, closely related to the Cornaceae (dogwood family). There is only one genus, '' Alangium'', with seventeen species. The APG II states that Alangiaceae is a synonym of Cornaceae The Cornaceae are a cosmopolitan family of flowering plants in the order Cornales.

Nyssaceae is a family of flowering trees sometimes included in the dogwood family (Cornaceae). Nyssaceae is composed of 37 known species in the following five genera:Averyanov, L. V. & Hiep, N. T.

Pseudanthium
A pseudanthium (Greek for "false flower"; ) is an inflorescence that resembles a flower. The word is sometimes used for other structures that are neither a true flower nor a true inflorescence. Examples of pseudanthia include flower heads, composite flowers, or capitula, which are special types of inflorescences in which anything from a small cluster to hundreds or sometimes thousands of flowers are grouped together to form a single flower-like structure. Pseudanthia take various forms. The real flowers (the florets) are generally small and often greatly reduced, but the pseudanthium itself can sometimes be quite large (as in the heads of some varieties of sunflower). Pseudanthia are characteristic of the daisy and sunflower family (Asteraceae), whose flowers are differentiated into ray flowers and disk flowers, unique to this family. The disk flowers in the center of the pseudanthium are actinomorphic and the corolla is fused into a tube. Flowers on the periphery are zygomor ...

Coniacian
The Coniacian is an age or stage in the geologic timescale. It is a subdivision of the Late Cretaceous Epoch or Upper Cretaceous Series and spans the time between 89.8 ± 1 Ma and 86.3 ± 0.7 Ma (million years ago). The Coniacian is preceded by the Turonian and followed by the Santonian. Stratigraphic definitions The Coniacian is named after the city of Cognac in the French region of Saintonge. It was first defined by French geologist Henri Coquand in 1857. The base of the Coniacian Stage is at the first appearance of the inoceramid bivalve species '' Cremnoceramus deformis erectus''. The official reference profile for the base (a GSSP) is located in Salzgitter-Salder, Lower Saxony, Germany. The top of the Coniacian (the base of the Santonian Stage) is defined by the appearance of the inoceramid bivalve ''Cladoceramus undulatoplicatus''. The Coniacian overlaps the regional Emscherian Stage of Germany, which is roughly coeval with the Coniacian and Santonian Stages ...

It is the second most populous country in Europe after Russia, and the most populous member state of the European Union. Germany is situated between the Baltic and North seas to the north, and the Alps to the south; it covers an area of , with a population of almost 84 million within its 16 constituent states. Germany borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its financial centre is Frankfurt; the largest urban area is the Ruhr. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
